Title: Lighting equipment for aged-person and projector
Inventor: YANO TADASHI
IPC: F21S4/00
Filed: 1990-09-26
Abstract: PURPOSE:To obtain lighting equipment for an aged-person which has high brightness and less glare and a projector by setting the ratio of radiant flux in a wavelength area of 470-530nm to radiant flux in a visible wavelength area (380-780nm) to be 135 or more and less than 21%. CONSTITUTION:Radiant flux in a wavelength area of 470-530nm is easily dispersed in aged-person eyes. Since standard light (illumination light with spectral power distribution approximating to day light of color temperature 5350K) has the ratio of radiant flux in a wavelength area of 380-475nm to radiant flux in a visible wavelength area of 380-780nm is 21%, the ratio is set to be less than 21% to reduce dispersion and restrain glare. If the ratio of radiant flux in a wavelength area of 470-530nm to radiant flux in a visible wavelength area is set 13% or more, color rendering properties can be secured.

Abstract: PURPOSE:To prevent a film from curing and to improve it in reliability as to dimensional stability, adhesive force, and the like by a method wherein polymide resin layers different from each other in thermal linear expansion coefficient are applied onto a conductor making the resin layer of higher thermal expansion coefficient face outward, which is dried up to be set in a pressure reduced and/or a reducing atmosphere to form a multilayered insulator. CONSTITUTION:A copper plated laminated board is manufactured in such a method that at least two types of polyimide resin compositions or their precursor compositions different from each other in thermal linear expansion coefficient are applied onto a conductor making a resin layer of higher thermal expansion coefficient located outside, which is dried up to be set in a pressure reduced and/or a reducing atmosphere. It is preferable that the linear expansion coefficient difference between the high thermal linear expansion resin layer and the low thermal linear expansion resin layer is larger than 510(1/K) or above. It is also preferable that a resin applying method is carried out in such a manner that two more kinds of polyimide resin or their precursor solutions are applied onto a conductor at the same time using a multilayered die. By this setup, even if a heat hysteresis is given to a copper plated laminated board of this design, it is free from curling, torsion, warpage, and the like, can be secured enough in adhesion, flexibility, dimensional stability, and the like, and can be made small in curling after the etching of a conductor so as to be improved in workability.

Title: Gate system of photothyristor with overvoltage protecting function
Inventor: INO HIDETOSHI
IPC: H02M1/00
Filed: 1984-12-07
Abstract: PURPOSE:To prevent a photothyristor from damaging by switching to a healthy optical gate light emitting diode rapidly even if a phototrigger thyristor is fired due to a defect of the diode. CONSTITUTION:Light emitting diodes 8-1,...,8-N connected in parallel with photothyristors 6 apply a light signal to a photoreceptor 12 when a voltage higher than the prescirbed value is applied to the thyristor. Thus, since only the diode 8-2 connected with the photothyristor 6-2 generates a light signal, a '1' output is produced only for the signal 2b converted by the photoreceptor 12 into an electric signal. Thus, when at least one signal of signals 1b-Nb is different from other signals, an incoincidence signal C is generated from an incoincidence detector 13. This signal C closes a switch 14 to switch a DC power source 1 connected with light emitting diode group of a system A with light emitting diode group of a system B.

Abstract: PURPOSE:To secure an appropriate supply voltage for a gate-driving circuit by obtaining from a first DC power supply a power for the driver circuit of a so-called chopper-type inverter switching element converting a second DC voltage into a poly-phase AC voltage. CONSTITUTION:As a DC power supply for gate-driving circuits 4a, 4b...4e, the positive side terminal of each of the circuits is connected with the positive side of the front stage side of a DC conversion inverter circuit including a chopper-switching(SW) element 1, etc., and the negative side terminal thereof, with the negative side of the inverter circuit. Because the constant voltage of a DC power supply E is always applied to the front stage side of the inverter circuit, the gate-driving circuits are also supplied with a constant voltage. The supply voltage of the gate-driving circuits can drive always stably the gate of a three-phase AC conversion chopper-type inverter SW element without being affected by the operation of the chopper-SW element 1.
